Research Interests

Humans evolved slowly over the course of millions of years. Our bodies evolved, primarily, to cover large distances in our bare feet while hunting and gathering. Our environment tended to change slowly around us until the advent of agriculture, the industrial revolution and most recently, the internet. This has led to a rapid change in our environment that our bodies are not equipped for. High sugar diets, modern footwear, concrete, excessive screen time and a lack of exercise contribute to modern illness. Our research focuses on differences in foot structure and function between those who have grown up with and without shoes. We seek to understand what the consequences of modern footwear use are for movement skills and injury risk. We also seek to determine what happens when people transition from modern footwear to barefoot or minimalist shoe activities. We have a number of projects taking place with children and adults, including those with existing musculoskeletal conditions.

Engagement and Collaboration

Dr Francis has worked as a performance science and medicine consultant to the Athletics Association of Ireland since 2011, which has involved coach education and providing training camp support to athletes abroad. He was awarded a 6-month research sabbatical at the Sports Research Institute New Zealand (SPRINZ) located in Auckland University of Technology. During the sabbatical he noticed cultural differences in barefoot activities among New Zealanders and in particular, during a secondary school athletics event on the track next to his office. He designed and carried out a study to determine the prevalence of barefoot activity among New Zealand boys which has since been published. 

Dr Francis has received €80,000 in research funding from minimalist footwear company Vivobarefoot to investigate differences in foot structure and function between children who grow up with and without traditional footwear.
